Product Details:

KOLLMORGEN 6SM37L-4.000 is a compact permanent magnet synchronous servo motor from the classic Kollmorgen Seidel 6SM series, fitted with resolver analog feedback and keyway shaft. It is rated 0.5kW continuous power, 4000 rpm rated speed, 1.2Nm rated torque and 1.5Nm standstill torque, matched for medium dynamic positioning axes on legacy transfer and machine tool systems. This is an obsolete discontinued model, and most available units in the spare parts market are surplus or refurbished replacement stock.

This servo motor uses resolver feedback to transmit rotor angle and speed signals to matched Kollmorgen SERVOSTAR servo drives for closed-loop speed and position control. Resolver structure offers strong resistance to vibration and dust interference compared with optical encoders, which is suitable for harsh workshop environments. It needs homing operation after power cycle to establish position reference. Separate power cable and feedback cable connectors reduce electromagnetic noise interference inside industrial electrical cabinets equipped with inverters and switching components.

This variant is non-brake design without integrated holding brake, suitable for horizontal transfer axes, packaging rotary feeders and machine tool auxiliary positioning slides where power-off locking is completed by external mechanical brake. The keyway shaft provides stable torque transmission with gearboxes and reducers and prevents slippage under fluctuating load. The stator winding adopts Class F insulation material and integrates built-in thermal sensor for real-time temperature monitoring to avoid overheating damage during long-time continuous operation. The motor housing reaches IP64 protection grade, resisting workshop dust and coolant splash. Optimized low cogging magnetic circuit suppresses torque ripple greatly, maintaining smooth rotation and stable repeat positioning accuracy.

It supports torque control, speed control and position control modes, and motion parameters can be tuned via Kollmorgen drive configuration software. Standard flange mounting dimension supports direct replacement for old equipment renovation without modifying mechanical structure. Every finished motor passes factory validation before shipment, including resolver signal calibration, speed stability test, insulation resistance inspection and vibration endurance test to guarantee stable performance in multi-shift transfer and machine tool production lines.

It is widely deployed on automated transfer lines, small machine tool auxiliary axes, packaging rotary transfer equipment, material cutting positioning stations and printing machinery driving modules. Typical application axes include horizontal conveyor positioning units, rotary indexing turntables, feed driving modules and precision adjustment platforms. Automation integrators select this 6SM series resolver variant for its robust anti-vibration performance, compact power density and seamless compatibility with Kollmorgen SERVOSTAR drive systems.
